Module: Nortel-MsCarrier-MscPassport-ApsMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-ApsMIB::mscApsModeMismatchAlarm

OID (numeric): 1.3.6.1.4.1.562.36.2.1.134.13.1.10

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This attribute indicates whether the Aps component is experiencing an APS mode mismatch alarm (code 7011 5272). This alarm indicates either:

(1) that the far end is operating with a 1:n switching architecture (not supported by Passport), as opposed to 1+1; or

(2) that the far end's provisioned mode is not the same as the nears end's provisioned mode.

When a mode mismatch occurs: (1) if the far end is operating with a 1:n switching architecture it will operate as 1+1; and (2) if either end has a provisioned mode of unidirectional then both ends will operate unidirectionally.

What is mscApsModeMismatchAlarm?

This read-only value (on/off) reports whether the Aps component has an active mode mismatch alarm, meaning the far end is using an unsupported 1:n switching architecture or its provisioned mode (unidirectional/bidirectional) doesn't match the near end's. An 'on' value means both ends may silently fall back to unidirectional operation, which is worth confirming matches your intended design.
